One of the most commonly-used pesticides in the world was recently declared a probable cause of cancer—but that doesn't mean what you think, and here are some stick figures to explain it to you.

This video by Andrew Maynard of the University of Michigan's Risk Science Center explains what exactly the word "probably" means in that context (it has a specific definition). It doesn't mean that the substance is a carcinogen and it will probably give you cancer; it means that it's probably a carcinogen that may or may not ever give anyone cancer. If that's confusing, don't worry; the stick figures will make it all clear.
